first embodiment
[0081]The controller 60 controls actuation of the actuator 16 of the forward movement holding mechanism 12 and the inflator 33 based on signals from a collision predicting sensor 61 (see FIG. 1) and a turn sensor 63 (see FIG. 3). The collision predicting sensor 61 is constructed using ultrasonic waves, radar, or the like that enables predicting a collision of a pedestrian with the vehicle V, and disposed at a plurality of places of a bumper 3. The turn sensor 63, which detects an upward or downward turn of the forward movement holding mechanism 12, is formed of a microswitch or the like arranged at the part of the stopper 27, 28 and to be turned on at the time of contact with the housing 17 in the case of the Also, as the turn sensor 63, a sensor such as a contact sensor or an optical sensor that is arranged around the holding shaft 22 and capable of detecting a turn of the holding shaft 22 itself may be used.
[0082]And, the controller 60, when having predicted a collision of a pede...
second embodiment
[0098]In the second embodiment as well, when the vehicle V is about to collide with a pedestrian, because the controller 60 predicts a collision of the vehicle V with the pedestrian based on a signal from the collision predicting sensor 61, the controller 60, first, as shown by alternate long and two short dashed lines in FIG. 12 and in FIGS. 14A and 14B and FIGS. 16A and 16B, actuates each actuator 16A of the forward movement holding mechanism 12 to cause a forward movement of the contact body 10 from the initial position P0 to the forward position P1 where the contact body 10 can contact the pedestrian. Then, the pedestrian hits against the contact body 10, and in response to the magnitude of pressing force toward the upper portion 10a or toward the lower portion 10b of the contact body 10, as shown in FIGS. 13A and 13B, the forward movement holding mechanism 12 rotates to one side of upward or downward.
[0099]At this time, in the pedestrian protection system S2 of the second embod...
third embodiment
[0106]In the third embodiment as well, because the airbags (upper / lower) 77, 81 serving as restraint bodies are actuated so as to be able to selectively protect a pedestrian MU moving to the front upper side FU of the vehicle V or a pedestrian MD moving to the front lower side FD of the vehicle V, the restraint bodies can be formed small, so that it becomes possible to construct the pedestrian protection system S3 with remarkably lightweight and small size.
[0107]Also, the restraint body for receiving a pedestrian moving to the front upper side or front lower side of a vehicle is not limited to an airbag that makes an inflating gas flow in and projects from a storing part to inflate, as long as it can protectably receive a pedestrian. For example, as in a pedestrian protection system S4 of a fourth embodiment shown in FIGS. 20A, 20B and 21, a plastically deformable hood panel 7A may be used as the restraint body that receives a pedestrian MU moving to the front upper side FU of the v...
